How does one go about setting up the equations used for this question step by step?
Thanks!

Re: 15.35
We cannot simply multiply the half life by a factor of 4 because the half life of a second order reaction is reliant on the initial concentration of the reactant (while the first order half life reaction only relies on the equilibrium constant.)
Second order half life equation: 1/k[A]o
First order half life equation: ln2/k
Second order half life equation: 1/k[A]o
First order half life equation: ln2/k

Re: 15.35
why is the fraction subtracted from 1 when we asking for the time for the concentration to reach that value of the initial? subtracting implies that it is the remainder after the said fraction gets used up in the reaction.

Re: 15.35
Use the half-life equation for the second-order reaction. then substitute A for the fraction of A naught.
